I come from a place that have plenty of expats and they never integrate well, their kids go to private schools and quite a number simply move back to EU/US. Meanwhile a large numbers the locals including myself are leaving due to political crackdowns, and expats simply live in a privileged society and don't get what's going on.

Depending on where you go, there's a chance you might get stuck there and not making enough to move back out. Some of those who move out ran out of funds and eventually went back with most of their live savings gone.
